The Safe Dreams Swaddle by HALO replaces loose blankets in the crib that can cover your baby's face and interfere with breathing. In addition to helping your baby sleep safer, it helps him sleep better, too. Its easy-to-secure swaddle wrap immobilizes your baby's arms to prevent the "Moro" or startle reflex. Discontinue swaddling when the baby shows signs of rolling over or breaking out of the swaddle. Size newborn fits 6
